Try changing DRAM to manual and set to 1600, in your second pic change the first 4 there from the 9-9-9 etc to the above 11-11-11-30 I mentioned
I still can't change the frequency to 1600 MHz, I tried to pick a value and then go up and down with the +/- keys, but the listed frequencies are the only ones available. There must be a way to set it to 1600 MHz manually, right?
